To all whom at may concern.'

Be it known that l, AUGUST E. KUTSCH- nacrr, a citizen of the UnitedStates, residing at Houston, in the county of Harris and State of Texas,have invented certain new and useful Improvements in. umps, of which thefollowing is a specication.

This invention relates to new and useful improvements in a pump.

The object of the inventionis to provide a pump of the characterdescribed adapted to be used in oil or water wells for pumping out thesand and slush after the well has been completed and the chief featureof the pump consists of /the provision of means whereby water will bedriven through the valve cage and against the valve seat an will keepsaid cage and seat free from sand. ln pumps now in common use for thispurpose, the sand and other detritus is dis,- posed to collect in thevalve cage and clog the valve and prevent it from working, and toobviate this defect the pump herein described has been provided.

lilith the above and other objects in view the invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings, wherein:

Figure 1 is a. fragmentary vertical sectional view of the upper part ofthe pump,

Fig. 2 is a fragmentary vertical sectional view of the lower partthereof and Fig. 3 is a. transverse sectional view taken on the line a-aof Fig. 1.

Referring now more particularly to the drawings, the numeral 1designates the pump barrel, which is attached at its upper end to thelower end of the pipe 2, whic extends up through the bore to thesurface. The lower end of the barrel is contracted slightly, asv at e,and a correspondingly tapered valve seat 5 is fitted therein having theopening 6 therethrough, which is controlled by the ball valve '7.Surrounding this seat is a flexible washer 8, which rests against thepump barrel and prevents leal;- age and upstanding from the. seat 5 is acage 9 provided toretain the valve in position. ln the upper'part of thebarrel is a hollow lunger 10, whose upper Vend is formedinto a seat 11.having the'passage- Specification o'l Letters Patent.

controlled position by has the way 12l therethrough,` which is bytheball valve 13, retained in the valve cage 14;, whose head opstandingoutwardly threaded tubular nipple 16,' whereon the lowerend of thetubular plunger rod 17 is threaded. The plunger is provided with aplurality of cup-shaped Washers 18, of well known construction, toprevent leakage therearound. rl`he lower end of the plunger isinternally threaded as at 19 to receive the externally threaded neck 20,which upstands from the head of the cage 9. llhen it is desired towithdraw the seat 5, the plunger may be lowered and screwed on to theneck 20 and the plunger and `seat may then be withdrawn together.'

dvA

pair of small pipes, as 21, 21, are provided, whose upper endscommunicate with the interior of the barrel at its upper end and whoselower ends communicate with of the barrel just above the seat 5. Withinthe bore is the ordinary well casing 22, somewhat. larger in diameterthan the pump barrel and whose lower end carries the well screen 23,provided with openings to permit the inflow of the duid. Attached to thelower end of the barrel is a short perforated pipe section 24, whoselower end is plugged up and rests upon the bottom of the bore tosustain'the pump -while in action, although this pipe section is notindispensable tothe operation of the pump. rlChe plunger rod 17 isactuated by a suitable motive power from the surface of the ground andby this means the plunger is reciprocated up and down. As the plungermoves upwardly, the v lve 13 is seated and the valve 7 lifted,permitting the barrel to fill with fluid and lifting the fluid above theplunger and forcing it to the surface. When the plunger is lowered thevalve 7 is seated and the valve 13 lifted, permitting the fluid to passabove the plunger. llure wat-er may be forced from the surface throughthe plunger 'rod 17 down into the cage 1e, which will keep said cage andthe valve therein freed from sand' and the like which would otherwisecollect thereon. This water is also forced through the pipes 21,21 anddischarged into the cage 9, thereby freeing said cage and the va vetherein from sand as above explained.

, 'Upon the` up stroke of the plunger a certain amount of fluid willpass from. the barrel through the pipes 21, 21, and be dischargedagainst-the cage 9 and Will operate to Vcleanse said cage and valve.

What I claim is: A pump including a barrel, a valve cond trolling theinflow of fluid into one end thereof7 a plunger having n, Huid passage-Way therethrough arranged to reciprocate inv the barrel, avalvecontrolling said passageway, a hollow plunger rod connected to andprovided to reciprocate said plunger through which Huid may bedischarged :,igainst said valve. and a fluid conduit com municating:it-its respective ends With the interior of said barrel on oppositesides of l5 :aid plunger, and through which Huid may lle driven againstthe barrel seat.

In testimony whereof I have signed my naine to this speeication in thepresence of p awo subscribing Witnesses.
